Abstract

PURPOSE:To reduce space and equipment costs by moving a sliding table itself from a stacking device by the reaction of the sliding friction generated between the steel plate under conveying and driving rolls. CONSTITUTION:When a sliding table 2 is located above a stacking device 7, and a steel plate 5 is conveyed onto the table 2 with a conveying roll table 1, the plate 5 is stopped above the device 7 by a steel plate stopping device 4. When the driving rolls 2a on the table 2 are rotated and driven in the direction reverse from the conveying direction (a) of the plate 5, the movement of the plate 5 is prohibited by a preventing device 6 for stray running and the force for moving the table 2 in the direction opposite from the rotating direction of the rolls 2a is acted by the reaction of te sliding friction generated between the plate 5 and the rolls 2a. Therefore, the table 2 moves the plate 5 in the conveying direction while bringing the plate 5 to fall gradually from one end thereof onto the device 7 so as to allow the plate 5 to remain in said position. When the end part of the plate 5 leaves the final roll 2a on the table 2, the plate 5 is contained on the device 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel plate stacking device that is applied when stacking steel plates manufactured by continuous casting equipment, rolling equipment, etc. in a predetermined position.

Conventional techniques for sending steel plates carried by a roller table from manufacturing equipment to a stacking device are usually a method in which the steel plates are hoisted by a crane or the like using a hanging bracket, a method in which they are pushed out from the side of the roller table onto the stacking device using a pusher, etc. For example, a method is adopted in which the material is slid down an inclined pedestal provided at the end or side of a roller table and dropped onto a stacking device.

All of these methods require a large amount of space for the entire equipment, and in those that use lifting fittings, the operation cycle of the crane that transports the lifting fittings may not match the transport cycle of the steel plate being carried, or the lifting fittings may When hung, there is a risk of damaging or deforming the steel plate. In addition, the method of sliding on an inclined pedestal has the disadvantage that it causes scratches on the surface of the steel plate, resulting in a significant loss of product value.

The present invention has been made for the purpose of eliminating these conventional problems, and will be described below based on embodiments shown in the drawings.

(2) is a conveying roller table, and the table at the end thereof is a sliding tape/I/2 that can move forward and backward in the conveying direction of the steel plate, and is supported on a guide tray (v3) so as to be freely movable. Further, the drive roller 2a on the tape/I/2 has a drive device so that it can rotate in forward and reverse directions. Reference numeral 4 denotes a steel plate stopping device provided at the tip (right end in the figure) of the sliding tape/l/2, which serves to prevent the conveyed steel plate 5 from overrunning. To,
If a stopping device such as a brake is provided, it may be omitted.

Reference numeral 6 denotes a steel plate reverse running prevention device, which is provided to prevent the steel plate 5 carried onto the sliding table 2 from running backwards. The steel plate backfeed prevention device 6 is provided at the end of the conveying roller table 1, and when the steel plate 5 is fed onto the sliding table 2, it is evacuated so as not to interfere with the feeding. The structure is as follows. Stacking device 7 installed directly below the sliding table 2
is connected to a lifting device 9 provided on a plurality of frames 8,
It can be freely raised and lowered by the synchronous drive of the lifting device 9.

The structure of the present invention is as described above, and in order to stack steel plates, first, a sliding tape/l/2 is applied to the stacking device as shown in the figure. With the steel plate in the upper position, the steel plate is placed on a sliding tape using a transport roller tape.
Once conveyed onto I/2, the steel plate 5 is stopped above the stacking device 7 by the steel plate stopping device 4.

Next, when the driving roller 2a on the sliding table 2 is driven to rotate in the direction opposite to the conveyance direction a of the steel plate 5, the steel plate 5 tries to move in the direction opposite to the conveyance direction a of the steel plate, but the reverse movement prevention device 6 prevents the steel plate 5 from moving in the opposite direction. Its movement is blocked, and a reaction force due to sliding friction generated between the steel plate 5 and the drive roller 2a acts to cause the sliding tape /l/2 to travel in the direction opposite to the rotational direction of the drive roller. Therefore, the sliding tape/I/2 is a device that gradually stacks the steel plates 5 from one end. While dropping it upwards, that is,
The steel plate 5 is moved in the same direction as the conveyance direction, leaving only the steel plate 5 at the position.

When the end of the steel plate 5 separates from the last driving roller 2a on the sliding tape (vQ), the steel plate 5 is completely stored on the stacking device 7. When this operation is completed, the stacking device 7 is lowered by the thickness of the steel plate 5,
The sliding table 2 is constructed so as not to interfere with the steel plate 5 even if it is returned to its original position.

Stacking device by repeating the above operation? When the number of upper steel plates 5 reaches a predetermined number, the sliding tape)v
2 stacking device? After being moved from above, the stacked steel plates 5 are lifted to a predetermined location by a crane or the like.

Note that the operation for returning the sliding tape (vQ) to its original position may be performed manually or may be performed using an electric motor. When an electric motor is used, it is advantageous that the electric motor for the drive roller can be used at low equipment cost by appropriately using a switching device, a transmission mechanism, etc. using well-known technical means.

As described in detail above, in the present invention, since the stacking device is installed directly under the conveying roller table, it is very compact in terms of space. The equipment can be omitted, which not only greatly reduces equipment costs, but also reduces the transportation distance for cast slabs that require reheating in the subsequent process, reducing temperature drop, which is extremely energy-saving. It is effective, and furthermore, since the sliding member such as the inclined pedestal of the prior art is eliminated, there is no risk of damaging the surface of the steel plate, etc., and the drawbacks of the conventional device are eliminated, and the purpose of the invention is definitely achieved.
